LOCOMOTIVE TENDER/t Application filed March 10, 1924. Serial No. 698,130.

To all whomitmwg concern Be-it known that I,, R0BERT V. ANDERSON, a citizen of the UnitedStat'egand a resident ofSchenectady, in the county of Schenectadyand State of New York, have invented a certain new and useful Improvement in Locomotive Tenders, .ofwhich improvement the following is a. specification. 1

My invention relates to locomotive tenders having a water cistern of cylindrical form, an early instance of which is exemplified in tenders constructed for a railroad in Germany, and illustrated in the technical publication entitled Organ fiir die Fortschritte des Eisenbahnwesens in Technischer Beziehung, l/Viesbaden, 1846, Band 1,

'Taf. 5, Figs. 1, 2 and 3. The cylindrical water cistern has, in later years, been applied, to a considerable extent, in tenders of the so-called Vanderbilt type, set forth in Letters Patent of the United States No. 681,760, dated September 3, 1901.

The object of my invention is to economize and facilitate the manufacture of locomotive tenders of the type above specified, by overcoming structural difficulties encountered therein, as heretofore conducted, which protract the operation and tend to impair the perfection of the finished water cistern.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings: Figure 1 is a side view, in elevation, of a locomotive tender, embodying my invention; Fig. 2, a vertical transverse section through the same, on the line a a of Fig. 1; and, Fig. 3, a view, in perspective, on a smaller scale, of the water cistern and fuel box, detached.

In locomotive tenders of the type to which my invention relates, the forward portion of the cylindrical water cistern is truncated at its top, to provide space for the insertion of a fuel box, of greater width than the diameter of the water cistern, the fuel box extending horizontally above the lower portion thereof, for some distance from its front, and having its bottom thereafter upwardly and rearwardly inclined to the top of the water cistern. The horizontal and the inclined bottom plates of the fuel box, form walls of the forward portion of the water cistern, through the part of its length which is cut away for the reception of the fuel box, and water tight joints of said plates with the water cistern, are therefore requiredi Ithas heretofore been, and now is, the usual practice to'maketlie joint between the inclined rear plate of" the fuel box and the water cistern, b'ythe application of a structural steel anglesliape', but

it will readily be seen that whcre, ,aso in prior andordin'ary present practice", the adjoining portion of the water cistern is cylindrically curved, angles of peculiar shape are required, and it is difficult to properly fit them, and to drive and head the rivets, so as to ensure a water tight joint.

The objections above stated are overcome by my invention, under which the curvilinear joints of prior practice between the water cistern and the fuel box, are eliminated, and are'substituted by straight line joints, to which 90 degree angle bars are applicable.

My invention is herein exemplified as applied in a locomotive tender, having a cylindrical water cistern, 1, which is secured on a frame, 2, mounted on two four wheeled trucks, 3. The forward portion of the water cistern is, as heretofore, truncated or recessed, and a fuel box, 4, is fitted on the top of the recessed portion, the rear plate, 4*, of the fuel box, being upwardly and rearwardly inclined, and forming the top closure of the adjacent portion of the'water cistern. The construction thus far described, accords with that which is well known, and has become a standard, in the art.

In the practice of my invention, referring descriptively to the specific embodiment thereof which is herein exemplified, the portions, 1*, of the shell or wall of the water cistern, which extend above the bottom line of the fuel box, 4, from the front to the back of the inclined rear portion thereof, which shellportions are of substantially triangular form, as indicated by the lines a, b and c, in Fig. 1, are not, as in prior practice, curved concentrically with the remainder of the shell of the water cistern, but instead of being so curved, are extended in substantially vertical planes, to the inclined rear plate, 4 of the fuel box, and are connected to said rear plate by straight angle bars, 1

The practical advantages of my invention will be manifest to those familiar with the construction of locomotives and their tenders, in the particulars of avoiding all curved bending of structural angles, and difficulties in properly driving and heading rivets, thereby reducing time and cost in manufacture, and also ensuring more perfect water tight joints in the water cistern.

I claim as my invention and desire to secure by Letters Patent:

1. A cylindrical water cistern, for locomotive tenders, the upper forward part of which is recessed or truncated, and the side portions of the shell, in the recessed part, above the axial line, extend in substantially vertical planes.

2. Avcylindrical water cistern for locomotive tenders, the upper part of which is horizontally recessed or truncated, from its front, for a part of its length, and thence in an upwardly and rearwardly inclined plane, and the side portions of the shell above the axial line, in the length below the inclined part of the recessed portion, extend in substantially vertical planes.

3. In a locomotive tender, the combination of a water cistern, the forward portion of which is recessed, first horizontally and thence in an upwardly and rearwardly inclined plane, and the side portions of the shell are extended in substantially vertical planes for the length belowthe inclined part of the recess; a fuel box fitting in the recess; and straight structural angle shapes, connecting the fuel box to the water cistern.
